Hi Andre,

this is not my "bug", but seems to be very similar. If you point me to
instructions for "log with +call trace enabled" I should be able to
get that done (given that it doesn't disclose confidential data, the
email which I would use as an example doesn't contain any secrets, but
it's not public either).
